Title: Profiled bar clip for plastics or paper foils - is for foils with inner serrations on V:shaped profile and outer serrations on mating profile
Inventor: NAUMANN WILLI
IPC: B42F1/00
Filed: 1976-05-18
Abstract: A clip for foils of paper or plastics produces a reliable, easily detachable and air- and watertight connection which can be re-used repeatedly. One hollow profile (10) has a flange (14) by which it is fixed to a base (15). A second similar profile (11), made of plastics like the first, but with serrations on the outside instead of the inside, has an elastomer filling (13) to increase its springiness. The foil to be clipped is laid horizontally over the top of the profile (10) and the other profile (11) is pressed flat by a tool and inserted into the groove of the profile (10) thus folding the foil between them and fixing it.

Title: IC engine emission control system - has air from compressor cylinder passed to combustion chambers during power strokes and returned as mixt. for expulsion
Inventor: INGELN THEODOR KARL
IPC: F02B41/06
Filed: 1976-05-31
Abstract: The engine consists of two four-stroke cylinders and one two-stroke exhaust gas cylinder. Air only is compressed in the exhaust gas cylinder and passed at a temperature of 150 deg.C to 200 deg.C to the respective four stroke cylinder when its piston is half way through the power stroke. The compressed air mixes with the combustion gases to oxidise the residue CO and HC gases. The oxygen enrichened residual gases are then passed back to the exhaust gas cylinder via the exhaust valve when the respective pistons have finished their power strokes. The exhaust gas piston then begins its power stroke. The gases are finally expelled at atmospheric pressure via scavenging slots in the cylinder wall.

Title: Electronic filling level controller and indicator - has high-frequency coil producing alternating magnetic field wound directly on coil body
Inventor: WEIGL ROBERT
IPC: G01F23/26
Filed: 1976-09-06
Abstract: The high-frequency coil can have connected to it various resistors, whether ohmic, inductive or capacitive, in order to damp the oscillator. An adapter is used to switch from inductive to capacitive initiators. A coil is connected to two electrodes designed as an air capacitor and is brought into the field of an ordinary inductive proximity switch. This inductive switch is converted to a capacitive switch as a result of the electrical field present at the capacitor. The adapter can be combined into a single structural unit as a capacitive proximity switch.

Title: Continuous photometry measuring process - in which trays in holders on endless belt pass by transparency measuring unit
Inventor: VOIGT HANS
IPC: G01N35/02
Filed: 1976-12-10
Abstract: The process continuously measures processes detectable by photometry, having a series of tray holders mounted on an endless belt. The trays in the holders are intermittently passed by a single photometry unit, measuring and recording the degree of transparency of each tray in turn. Stirring is effected by a magnetic system, driven by a central motor. Heating of the inside of the photometer can be controlled by thermostat, while the driving wheels are moved by an indexing motor controlled by photoelectric cells. The motor stops automatically when a tray passes the cell, and cuts in again after measurement of transparency has taken place.

Title: Multi-rotor electric motor with cup-shaped stator - has interior and exterior rotors rotating at sync speed and same direction
Inventor: DROBINA DEZSO DONALD
IPC: H02K16/02
Filed: 1977-02-02
Abstract: The wound main rotor is mounted on a drive shaft which is rotatable within a cup-shaped stator, which is so wound that when connected to a source of polyphase power, it provides a rotating magnetic field. A second rotor equipped with permanent magnets is mounted for rotation about and outside the stator and tends to rotate at synchronous speeds in the same direction as the main rotor. The two rotors are normally connected for mutual rotation between starting speed and predetermined speed, less than synchronous speed, by a spring-loaded, centrifugally-opened clutch assembly which disengages when the main rotor reaches the predetermined speed so as to enable both rotors to rotate independently, and which re-engages both rotors for mutual rotation when the speed of the main rotor falls below the preset speed.

Title: Energy generator using water level differences - has float guided vertically in channel and connected to endless chain for driving generator at one end
Inventor: HARTWIG RUDOLF
IPC: F03B17/02
Filed: 1977-03-17
Abstract: The arrangement makes use of differences in water level to generate power, by allowing water from a higher lever to flow into and fill a shaft contg. a buoyancy element. The resulting upward movement of the element is transferred to an endless chain, cable or similar via hooks or similar members on the element engaging corresponding members on the chain. The chain wheel shaft drives a generator. Water flows into the shaft via the inlet valves which are closed when the water reaches its highest level, and outlet valves are opened. The chain continues to be driven by the element during its downward movement. The outflowing water may enter a lower-level shaft with similar mechanism.
